Abstract: The present invention relates to a papermaking machine and papermaking method that make paper web by removing moisture while making a paper stock layer travel, and the object of the invention is to dehydrate the paper stock layer more efficiently. A papermaking machine for making continuous paper web by holding a paper stock suspension 1a jetted from a head box 2 into the shape of a layer, and removing moisture while making this paper stock layer 1 travel. The papermaking machine is provided with steam type heating means 6 and adjustment means 11. The steam type heating means 6 is provided in a moisture removing part as heating means for heating the paper stock layer 1 to accelerate the moisture removal, and supplies steam to the paper stock layer 1 and heats the paper stock layer 1 by condensation of the steam.

Abstract: A clock signal generating device of the present invention has an active and a spare clock selecting circuit. The two clock selecting circuits each includes a selector for selecting one of a plurality of outside timing signals and outputting it as an inside clock signal under the control of a controller. A PLL (Phase Locked Loop) circuit is commonly connected to the outputs of the active and spare selecting circuits. The PLL circuit reduces the influence of switching between the active and spare selecting circuits and switching between the outside timing signals. The PLL circuit includes a hold-over circuit for temporarily holding, in response to a control signal fed from the controller, a signal output from the selecting circuit.
